If an SCO field is in the result, the projected field is not owned by any persistent instance, and modifying the SCO value has no effect on any persistent instance. If an FCO field is in the result, the projected field is a persistent instance, and modifications made to the instance are are reflected as changes to the datastore per transaction requirements.
